Early defoliation and nitrogen fertilization: effects on maize morphophysiology and production

Abstract Early-stage defoliation represents a mechanical stress with increasing relevance in intensive cropping systems. This study investigated the morphophysiological responses and compensatory capacity of maize subjected to early defoliation and nitrogen (N) top-dressing manag...

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession

ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fraction...

Iron mining tailings toxicity to the tolerant tree species Schinus terebinthifolia is related to leaf anatomy, photosynthesis, and growth under different pH levels

Abstract The reforestation of areas impacted by mining tailings is a growing necessity worldwide. Although there are works that investigate the tolerance of tree species to iron mining tailings, the effect of modifications in the pH of this pollutant remains unclear. This work ai...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Abstract Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O...

Surface Ligand-Dependent Kinetics of α-Lactalbumin Interaction with Gold Nanoparticles Investigated by SPR

Abstract Understanding the kinetic and energetic factors governing protein adsorption onto nanomaterial surfaces is essential for elucidating nanobiointerfacial processes. In this study, the interaction between α-lactalbumin (αLa) and gold nanoparticles (AuNPs) functionalized wit...

Fast adsorption of Mn2+ and Zn2+ on commercial LTA zeolite: kinetics, equilibrium, and preliminary reuse assessment

Abstract Commercial LTA-type zeolite was evaluated for the adsorption of Mn 2+ and Zn 2+ from aqueous solutions, with emphasis on the relationship between framework properties and adsorption behavior. Despite its very low BET surface area, the zeolite showed rapid and highly effi...

Systems biology analysis reveals miRNA–mRNA networks associated with cardiomyocyte responses to SARS-CoV-2 infection

Cardiac complications are common and clinically significant in COVID-19, yet their underlying molecular drivers remain poorly understood. Here, we integrate post-mortem histopathology with transcriptomic and microRNA (miRNA) analyses to delineate the regulatory architecture of SA...

Matrix-DependentPerformance of β-GlucanComposite Films Functionalized with Phenolics from Passion Fruit SeedWaste

Abstract The valorization of agro-industrial waste for producing sustainable and functional packaging is a key strategy within the circular economy and green chemistry. This study developed active antioxidant edible films by incorporating a phenolic-rich extract from yellow passi...

A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also org...
